In 1942 all the missionaries and their staff were arrested by the invading Japanesearmies, and were lodged in concentration camps. Peter continued to lead the faithful of his village as best he could, caring for the sick, Baptising and teaching the converts, helping the poor. When the War began to go against them, the Japanese began to repress the locals, forbidding Christianity, and pushing for a return to pre-Christian ways, particularly of polygamy. Peter opposed the regression, and was arrested in 1945 for conducting religious gatherings. Imprisoned in a cave, he was so well known, supported and beloved by those who knew him that he continued to be a source of strength to his people, and of annoyance to his captors. Martyr.
